## LDAP
|
||||
|
||||
To run LDAP tests locally, you require a container running OpenLDAP.
|
||||
The LDAP integration tests require [OpenLDAP][openldap] installed on the host machine. To run them, use `go test`:
|
||||
|
||||
Run OpenLDAP docker image:
|
||||
```
|
||||
export DEX_LDAP_TESTS=1
|
||||
go test -v ./connector/ldap/
|
||||
```
|
||||
|
||||
To quickly stand up a LDAP server for development, see the LDAP [_"Getting started"_][ldap-getting-started] example. This also requires OpenLDAP installed on the host.
|
||||
|
||||
To stand up a containerized LDAP server run the OpenLDAP docker image:
|
||||
|
||||
```
|
||||
$ sudo docker run --hostname ldap.example.org --name openldap-container --detach osixia/openldap:1.1.6

|
|||
1. Finding the user based on the end user's credentials.
|
||||
2. Searching for groups using the user entry.
|
||||
|
||||
## Getting started
|
||||
|
||||
The dex repo contains a basic LDAP setup using [OpenLDAP][openldap].
|
||||
|
||||
First start the LDAP server using the example script. This will run the OpenLDAP daemon and seed it with a initial set of users.
|
||||
|
||||
```
|
||||
./scripts/slapd.sh
|
||||
```
|
||||
|
||||
This script sets the LDAP daemon to debug mode, and is expected to print several error messages which are normal. Once the server is up, run dex.
|
||||
|
||||
```
|
||||
./bin/dex serve examples/config-ldap.yaml
|
||||
```
|
||||
|
||||
Then run the OAuth client in another terminal.
|
||||
|
||||
```
|
||||
./bin/example-app
|
||||
```
|
||||
|
||||
Go to [http://localhost:5555](http://localhost:5555), login and enter the username and password of the LDAP user: `janedoe@example.com`/`foo`. Add the "groups" scope as part of the initial redirect to add group information from the LDAP server.
|
||||
|
||||
## Security considerations
|
||||
|
||||
Dex attempts to bind with the backing LDAP server using the end user's _plain text password_. Though some LDAP implementations allow passing hashed passwords, dex doesn't support hashing and instead _strongly recommends that all administrators just use TLS_. This can often be achieved by using port 636 instead of 389, and administrators that choose 389 are actively leaking passwords.
